在PHP中的字符串比较条件的OO方式或功能方式-OOwayorfunctionalwayofstringcomparisonconditionalsinphp

What you are searching for a ways of abstraction. In this example you are repeating yourself in case analysis and this might be the best approach if the "do something" is very different and not consistent.

你正在寻找一种抽象方式。在这个例子中,你在案​​例分析中重复自己,如果“做某事”非常不同且不一致,这可能是最好的方法。

$map = [ 'success' => function () { return 1; }, 
         'foo'     => function () { return 2; }, 
         'bar'     => function () { return 3; }, 
         'bazz'    => function () { return 4; } ];
foreach ( $map as $search => $value )
{
  if (stripos($result, $search) !== false )
  {
    return call_user_func($value);
  }
}

In my example these could just have been constants and we could just return them instead of applying a function. In a functional pattern this would be like the function any in Scheme SRFI-1 except it returns it's true value:

在我的例子中,这些可能只是常量,我们可以返回它们而不是应用函数。在函数模式中,这将类似于Scheme SRFI-1中的函数,除了它返回它的真值:

// This function uses PHP 5.6 ellipsis
function array_any(callable $callable, ...$arrays) {
  if( count($arrays) == 1 ) {
      $args_zipped = array_map( function ($x) { return [$x]; }, $arrays[0]);
  } else {
      array_unshift( $arrays, null);
      $args_zipped = call_user_func_array( "array_map", $arrays);
  }
  foreach ( $args_zipped as $args ) {
    $result = call_user_func_array($callable, $args);
    if( $result !== false )
      return $result;
  }
  return false;
}

array_any( function ($search, $value) { 
               if ( stripos($result, $search) !== false )
                   return $value;
                   return false;
           },
           array_keys($map),
           array_values($map));

The function in itself uses linear update, but as you can see it works similar to array_map.

该函数本身使用线性更新,但正如您所见,它的工作方式类似于array_map。

This simple function would do that work:

这个简单的功能可以做到这一点:

function checkWord ($haystack,$needle){
foreach ($needle as $word) {
    if (stripos($haystack, $word) !== false) {
        echo $word." was found!
";
    }
    else{
        echo $word." wasn't found
";
    }
  }
}

checkWord("Hello what's up?",array('Hello','Huhud','up','?'));

This will output:-

这将输出: -

Hello was found!
Huhud wasn't found
up was found!
? was found!
